DIRECTIONS FOR USE
It is a violation of Federal law to use this product in a manner inconsistent with its labeling. Read all Directions for Use carefully before applying. Do not apply this product in a way that will contact workers or .other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation
Mode of action
F9310-7 contains pyroxasulfone which acts to inhibit very long chain fatty acid synthesis as a Group 15 (WSSA)/ Group K3 (HRAC) herbicide. It is a root and shoot growth inhibitor that controls susceptible germinating seedlings before or soon after they emerge from the soil. Any weed population may contain or develop plants naturally resistant to, pyroxasulfone and other Group 15 herbicides. Weed species with resistance to Group 15 may eventually dominate the weed population if Group 15 herbicides are used repeatedly in the same in the same field or in successive years as the primary method of control for targeted species. This may results in partial or total loss of control of those species by pyroxasulfone or other Group 15 herbicides.
Some weeds are known to develop resistance to herbicides that have been used repeatedly. While the development of resistance is well understood, it is not easily predicted. Therefore herbicides should be used in conjunction with resistance management strategies in the area. Consult the local or State agricultural advisors for herbicide resistance strategies. If weed resistance should develop in the area, this product used alone may not continue to provide sufficient levels of weed control. If the reduced levels of control cannot be
attributed to improper application timing, unfavorable weather conditions or abnormally high weed pressure, a resistant strain may have developed. To reduce the potential for weed resistance, use this product in a rotation program with other classes of chemistry and modes of action. Always apply this product at the recommended rates and in accordance with the use directions. For optimum performance, scout fields carefully and begin applications when weeds are small. If resistance is suspected, contact the local or State agricultural advisors.
Glyphosate Resistant Weeds
Some populations of weeds may be tolerant or resistant to glyphosate based herbicides: Applying F931O7 in a tank mixture with glyphosate for control of emerged resistant weeds larger than specified in Table 6 in a postemergence application may result in unsatisfactory control. Follow all directions, restrictions and precautions on the EPA-approved label for each product in the tank mixture.
F9310-7 can be applied in all tillage systems (conventional, reduced and notillage). F9310-7 can be applied in the fall or in the spring as a preplant, pre plant incorporated, preemergence, or early post emergence treatment for susceptible grass and broadleaf weeds in field corn, seed corn, sweet corn, popcorn, and soybeans. F9310-7 may also be used in double cropping and multiple relay inter-cropping.
When applying F9310-7 alone for post emergent weed control, apply before the weeds have reached the maximum height listed in Table 6. Application after weeds have reached the listed maximum height for control could result incommercially unacceptable weed control. For control of weeds in post applications larger than listed in Table 9 and for wider spectrum, apply in. tankmixture with herbicide(s) that are labeled for control of targeted weeds. Uniform spray coverage is necessary for optimum performance.
Application Instructions and Timings:
Moisture is'necessary to activate the active ingredient pyroxasulfone in soil for weed control. Dry weather following applications of F9310-7 may "reduce effectiveness. However, when adequate moisture is received after dry conditions, F9310-7 will control susceptible germinating weeds. F9310-7 may not control weeds that germinate after application but before an activating rainfall/ irrigation of at least !4 inch, or weeds that germinate through cracks resulting from dry soil. When adequate moisture is not received after F9310-7 application, weed control may be improved by irrigation or by shallow incorporation with a rotary hoe. Do not use oh peat or muck soils or mineral soils with 10% or more organic matter content. Refer to the;crop specific information section for specific application rates, timings and the restrictions and limitations by crop and use pattern. Crop seeds must be planted a minimum of 1 inch deep.
Application Precautions for Post Emergence Applications:
1. If applying F9310-7 post emergence, avoid applications when crop foliage is wet due to heavy dew, rain, or irrigation moisture. If F9310-7 is applied post emergence, shortly before or soon after rainfall, crop response can occur. Recovery from this response is rapid and normal growth is not delayed. Crop yields will not be impacted by this crop response.
2. Do not apply if crop is under severe stress due to drought, cold weather, hail, flooding, water-logged or compacted soil, disease, insect damage, nutrient deficiency (especially low nitrogen levels), or other causes.
3. Do not tank mix any chlorpyrifos containing insecticide with F9310-7 in post applications as crop injury, might occur.
4. Do not irrigate within 4 hours of a post emergence application of F9310-7. Rainfall or irrigation within 1 hour may wash F9310-7 off of the weeds during this period and may reduce post emergence performance;
5. Observe all precautions and limitations on the label of each product used in tank mixture with F9310-7.
• Do not apply this product through any type of irrigation system.
• Do not use flood irrigation to apply, activate or incorporate this product.
• Do not make more than 1 preemergence application to spring corn or soybeans.
• Do not harvest or feed field corn forage until 3.0 days after the last application of F9310-7 Herbicide.
• Do not harvest or feed sweet corn forage or ears until 40 days after the last application of F9310-7 Herbicide.
• Do not harvest or feed corn grain or stover (fodder) until 70 days after the last application of F9310-7 Herbicide.
• Do not graze or feed treated soybean forage or hay to livestock.
• The last.application for soybeans should be.made no later than 60 days c before harvest.
Use sufficient spray pressure and spray volume for accurate and uniform application. Refer to instructions for the spray equipment used to determine the actual minimum volume. The carrier may be either water or a sprayable fluid fertilizer. Do not apply this product without dilution in a spray carrier. Apply F9310-7 in a minimum of 5 gallons of water per acre or 20 or more gallons of sprayable fluid nitrogen fertilizer per treated acre for weed control applications. For postemergence applications, apply F9310-7 in a minimum of 10 gallons per acre of finished spray solution. If a dense crop and/or weed canopy is present, use up to 40 gallons of spray solution per acre.
Use nozzle types and arrangements that will provide optimum coverage while producing a minimal amount of fine droplets. Apply at a minimum of 3 gallons of finished spray per acre. Spray volumes greater than 3 GPA may be needed for dense weed populations or with dense crop canopies.
